BUG 7729: Remove redundant tunnel drop flow in table 110

- Remove methods: L2ForwardingService::programLocalTableMiss
  and L2ForwardingService::programTunnelMiss. Both methods
  generate the same tunnel drop flows in table 110.
  The drop flows for individual tunnels are not needed
  since there is a default drop flow in the same table.

- Remove the method L2ForwardingService::programVlanFloodOut
  which is not used.
